Answer:
12/8 = 1 and 1/2 or 1.5
Step-by-step explanation:
what you do is make 3/8 and then put 4/1 next to it. then you multiply across. so 3 *4 and 8 * 1 which product is 12/8 and then you can simplify which i have provided above.
Answer:
78.5
Step-by-step explanation:
Step-by-step explanation:
2.5 + 0.15p = 0.4p
0.25p = 2.5 (subtract 0.15p on both sides)
p = 10 (multiply 4 on both sides)
Answer: 16/9 or 1 7/9
Step-by-step explanation:
plug in the values
4 2/3 + 2/3 * 1/2
add the first two values
4 2/3 + 2/3 = 4 4/3 or 5 1/3
multiply 5 1/3 by 1/2
5 1/3 * 1/3 = 16/9 or 1 7/9
Answer:
<h3>D. P = 15 and Q = 15</h3>
Step-by-step explanation:
Put the values of P and Q to the equation Px - 45 = Qx + 75:
15x - 45 = 15x + 75 <em>subtract 15x from both sides</em>
-45 = 75 FALSE
In other cases, we get some value x.
Example:
A. P = -45 and Q = -75
-45x - 45 = -75x + 75 <em>add 45 to both sides</em>
-45x = -75x + 120 <em>add 75x to both sides</em>
25x = 120 <em>divide both sides by 25</em>
x = 4.8
